SPECIFICATION forming part of Letters Patent No. 455,399, dated July *7, 1891.

Application Vfiled February 16, 1891- Serial No. 381.687... (No model.)

To all whom it nmz/"concern:

Be it known that I, JOSEPH A. HEAD, a citizen of the United States, residing' at Green- Vfield, in the county of Highland and State of Ohio, have invented certain new and useful Improvements in Dumping-IVagons; and I do hereby declare the followingr to be a full, clear, and exact description of the invention, reference being had,to the annexed drawings,

1o which form a part of this specification..

My invention comprises a novel combination of devices for operating a pair of tilting boards or sections off/a dumping-wagon, the details .of the saine being hereinafter more x5 fully described, and pointedoutin the claims.

In the annexed drawings, Figure l isa side elevation of my improved dumping-wagon, one of the rear wheels and a portion of the main frame being broken away to expose some zo of Vthe operative parts. Fig. 2 is a vertical section of the wagon-bed, the tilting boards of the same being slightly inclined. Fig. 3 is a similar section, but showing said board tilted to dump the load. Fig. 4 is a detail View.

A represents the main frame of the wagon,

which is mounted upon anysuitable runninggear, and has journaled in it three transverse stop-beams B C D, of which beams the front one D has a lever E secured thereto, while 3o the rear beam B and central bealn C have, respectively, levers F G. These levers F G are relatively shorter than the lever E, and are coupled to the latter by a connecting-rod H. Furthermore, the beams C D are provided with curved bearings or cam-lifters c d, for a purpose that will presently appear.

I and .I are pivot-beams, also journaled transversely of the frame, and serve-to support the tilting boards or bottom sections K 4o L, said beams being furnished with levers M N, the lever M of rearsectionI being coupled VVto another lever O by a rod P. These levers N O are arranged as seen in Fig. 4, the lever N being mounted upon a square or non-circular portion j of the pivot-beam journal,

while the other lever O turns freely on a spindlej of said journal, and is secured in place by a washer and nut j.

R is arack attached to frame A, and hav- 5o ing a notch frfor a spring-catch e of lever E to engage there, and therebyI hold this lever in its normal or retracted position. (Seen in Fig. l.) l Y Sisa bar carried rearwardly from this rack l and having one or more stops s to arrest the rearward throw of levers N O,between which levers said bar is located, as seen in Fig. Il.; When my wagon is ready for loading, the levers N O are thrown forward until the front ends of the tilting sections K L come in contact with the cam-litters c d and rest irmly thereupon. Then lever E is thrown back to the position seen in Fig. l, thereby simultaneously bringing the beams B, C, and D up snugly against the under side of said sec- 6,5 tions, at which instant the catch el engages with the notch r and thus locks said lever. It is eviden-t the tilting' sections are now horizontal, as indicated by dotted lines in Fig. l, in which position said sections are sup- 7o ported upon the beams B, C, D, I, and J, all of which bear their proper proportion of the load. The wagon-bed is then filled in the 'usual manner, accidental dumping of its contents being prevented by the engagement of 7 5: catch e with rack-notch r; but when the load is to be emptied this catch is disengaged and lever E is thrown forward until it reaches the position indicated by the dotted line E in Fig. 2'.Y This act so rocks the beams B C D on their bearings as to cause the rear beam B to swing down to an almost verticall position, as represented in Figs. 2 and 8, thus letting the rear or heavier end of section K drop a slight distance, While at the same time 8:; the heavier end of section L falls past theV beam C, which preliminary tilting of said' sections is rendered more positive by the upward action of cam-lifters c d against the front ends of these bottoms K and L. The pn contents of either part of the wagon or of the entire load can then be discharged by swinging the levers N .O back to the position indicated by dotted lines N Oin Fig. 3, thus inclining the sections K L very steeply; but in some cases this action will be automatic the instant the first lever E is thrown forward. It will thus be seen that the dumping is effected entirelywith the levers, the power imparted to beam B bythe load resting thereon loo being transferred to the cam-lifter d by rod H, and the falling power of the front of beam C to the rear cam-lifter c thereby causing every part of the bottom K L to work on a balance and these front and rear sections to move simultaneously. By providing a central gate or'division T the load can be divided in two parts and accumulation of trash against the beam C be effectually guarded against. To bring all the parts back to their normal positions, grasp-levers N O throw them forward until the sections K L strike the now upturned cani-litters c d, and then hold said levers very firmly. Now throw 1ever E back, so as to rock the beams B C D, and letvsaid sections become horizontal and be locked in place by re-engaging the catch e with notch r.

I claim as my inventionl. A dumping-Wagon provided with a pair of tilting boards K L, and a pair of transverse stop-beams C D, operated simultaneously by a single lever, said beams being provided, respectively, with rearwardly-cu rved bearers or can1-lifters c d, that initiate the elevation of the front ends of said boards, all as herein described.

2. The combination, in a dumping-Wagon, of stop-beams B C D, levers E F G M N O, connecting-rods I-I P, pivot-beams l J, and tilting boards K L, which boards are mounted upon said pivot-beams, for the purpose described.

In testimony whereof I affix my signature in presence ot' two witnesses.
